I don't have any hard data, but I notice quite a large difference. Not only does a light make sneaking much more difficult, it seems monsters in dark places will beeline for a character carrying a light source.

Sound also makes a big difference. Gunfire brings all the nasties running in your direction, while you can often snipe at things with a boomerang and get away with it.

I'm not sure what you want exactly, but if you are looking for the light source from the Miner's Helmet, it is actually a FLAG in the .pro file. It can be used to produce a FIXED size light glow on items.

This flag has a dynamic position (depends on script/damage sections size) but you can access this flag by loading the prototype in 'arcanum factory' if you'd like.

RunAwayScientist: Cool to see you arround here, I'm sorry for quitting the project about cracking maps. In the end the other projects took all my time... :???:
